Final answer:
To calculate the drug dose in micrograms per minute for a client weighing 125 lb, convert the weight to kilograms and multiply by the dosage of 10 mcg/kg/min, resulting in a dose of 567 mcg/min.
Step-by-step explanation:
To calculate the amount of drug to be administered by the nurse in micrograms per minute for a client who weighs 125 lb, we need to first convert the client's weight from pounds to kilograms. We know that 1 kilogram equals 2.20462 pounds. Therefore, we divide the client's weight in pounds by 2.20462 to get their weight in kilograms:
125 lb ÷ 2.20462 lb/kg = 56.70 kg (rounded to two decimal places)
Next, we multiply the client's weight in kilograms by the ordered dose (10 mcg/kg/min) to find the dose in micrograms per minute:
56.70 kg × 10 mcg/kg/min = 567 mcg/min
So the nurse must administer 567 micrograms of the medication per minute to the client.
